Start with an item by Turtle Wax called Polishing Compound...its like wax but has tiny particles to remove very minut scratches, stains and haze!
It wont take out big scratches or scrapes, but it should remove the poo.
If that wont work, go to walmart and get some Oops from the paint department. Now be careful with this stuff!!!!!!!! It is an adhesive remover. Take a tiny bit on a rag and slowly rub in a cirular motion to remove the spot. AS SOON AS THE SPOT IS GONE WASH THE AREA WITH SOAP AND WATER!!!!!
If you dont it will eat through the clearcoat, color coat and primer!

Used properly this is some amazing stuff! Oh and when you debage your car it is the best sh*t in the world to remove the adhesive pads!
